查询词典 diversity

Diversity of endophytic fungi in leaves of Ginkgo biloba was studied in order to understand diversity state and succession change of endophytic fungal communities in this endemic plant. Healthy leaf samples were collected from five main planting locations of G. biloba in Jiangsu and Shandong provinces separately in spring, summer and autumn.

The results showed that the species richness,the speciesdiversity and its biomass of understorey vegetation decreased with the stand age in-creasing.There was the most significant negative-linear relationship between thiskind of changes and age.It is possible that the certain shading condition may benefit to understorey growing better.The richness,diversity index and biomass of thevegetation in eucalypt plantation decreased with CPR increasing,however,after ro-tating by watermelon one rotation,the richness,the diversity index and biomass ofunderstorey in CP stand increased,this result will provide the possibility of therestoration and reestablishment of vegetation in eucalypt plantations.The nutrientstorage of understorey decreased in accord with the productivity decreased withCPR increasing,this is the result which the stand enviroment became worse and thestand stratum competed with the vegetation for the water and fertility of soil.

结果表明，随着年龄的增长，桉树林下植被物种丰富度降低，多样性减少，生物量下降，这种变化趋势与年龄存在极显著的负线性关系；随着造林密度的增加物种丰富度降低，多样性也下降，但林下植被生物量尚有增加，可能是一定程度的庇荫有利于桉树林下植被的生长；随连栽代次的增加，桉树林下植被丰富度降低，多样性指数下降，生物量减少；但在轮作一茬西瓜后的林地，物种丰富度提高，多样性指数升高，生物量增加，为桉树林下植被的恢复与重建提供了可能性；随连栽代次增加，林下植被养分总量逐代下降，与生产力下降一致，这是林分环境恶化后上层乔木和林下植被对水肥竞争的结果。

According to the heredity diversity indexes described above of the five goat breeds, Guanzhong dairy goat had the most abundant heredity diversity and showed high polymorphism, and Xinong Saanen dairy goat and Shaannan white goat were inferior, while Angora goat and Boer goat had the lowest genetic variability.

分析结果显示，关中奶山羊的遗传多样性最丰富，表现为高度多态；其次是西农萨能奶山羊和陕南白山羊，而安哥拉山羊和波尔山羊的遗传变异程度最低。

Here, we examined the genetic diversity and phylogeographic structure of domestic goats by determining mitochondrial DNA and microsatellite DNA. The genetic diversity of five goat breeds including Angora goat, Shandonglaiwu black goat, Hanshan white goat, Taihang goat and Wuzhumuqin goat was surveyed using twenty-five microsatellite loci, The UPGMA phylogenetic trees constructed with the Dcoa genetic distances between the five goat breeds supported a closer relationship between Hanshan White goat and Wuzhumuqin goat.
